Poor advice on device

<p>I had upgraded my phone contract to an Iphone on the 26th of January. I was issued with the 32 gig , however I was not informed of the price difference between the 32 gig and 128 gig, I then went in to exchange this for the 128 gig and was told that I cannot exchange the contract. I was not informed and hence when making my decision I did not do it taking into consideration the other alternatives. As a result of poor advice I now have a device that I am not happy with. I have not dropped or damaged the phone in any way. I think that this is poor service and in violation of the consumer protection act as there is normally a 14 day cool off period. Please advice if anything can be done as this is a formal complaint, if not attended to I will have to escalate to the ombudsman.</p>
